In the later periods the viscera packets previously placed inside the body
were now often again placed inside stone canopic jars (Late Period) or tall
wooden canopic chests (Ptolemaic Period). In the Ptolemaic Period the mummification
became more widespread. The viscera remained in the bodies or the body was
filled with packets of resin soaked linen, mud, broken pottery molten resin
or with bitumen.

In the Roman period the mummification saw a further decline. The bodies are
often only badly preserved, and therefore it is often not possible to say
whether the brain or the viscera were removed. More care was applied to the
mummy wrappings, which were more elaborate than ever before; rhomboidal patterns
of bandages built up in several layers are found for both human and animal/bird
bodies.

Bodies were still being embalmed in the Byzantine period. The body may have
been treated with natron, as before, but now daily life dress replaced the
mummy bandages. Mummification came to an end with the Arabic conquest.
